When the outputs of 1, 99 and 105 are impossible outputs, for example, when the outputs of the second receiving unit 99 and the third receiving unit 105 are both larger than the output of the first receiving unit 91, that is, on the wall or the like. When the signal of the transmitter 84 is reflected and input, the input is invalidated so that the signal does not operate.

Then, in step S18, the direction of the transmitter 84 is calculated from the ratio of the outputs of the first, second and third receivers 91, 99 and 105. The calculation result may deviate from the actual direction of the transmitter 84 depending on the strength of the infrared signal. Therefore, the strength of the infrared signal is detected based on the outputs of the first, second, and third receivers 91, 99, 105 and the output from the AGC amplifier 97, and the detection result is corrected according to the strength of the infrared signal. Then, the direction of the transmitter 84 is calculated.

In step S19, the left and right swing motor 43
Is driven, that is, it is determined whether left / right swing is performed. If left / right swing is performed, the process proceeds to step S20 and it is determined whether upper / lower swing is performed. If vertical swing is performed in step S20, the process moves to a swing center movement motor drive routine, which will be described later, and if vertical swing is not performed, the swing center shift motor drive routine is executed and vertical swing is performed. The electric motor 80 is driven to swing the fan head 69 up and down.

If the horizontal swing is not performed in step S19, it is determined in step S21 whether vertical swing is performed, the process proceeds to step S22 or step S23, and is calculated in step S18 in step S22 or step S23. It is determined whether or not the direction of the transmitted transmitter 84 is within a range in which the fan head 69 can be directed to the transmitter 84 by driving the swing center moving motor 12, and the rotation by the swing center moving motor 12 is performed. If it is within the range, it is determined in step S24 or step S25 whether or not the fan head 69 is stopped in a state of facing the front of the swing center adjusting body 50. If the fan head 69 is stopped in the state facing the front of the swing center adjusting body 50 in step S24, the process moves to the swing center moving motor drive routine. Step S22
If the fan head 69 is not within the range in which the fan center moving motor 12 can direct the transmitter head 84 to the transmitter 84 in step S23, or if the fan head 69 moves to the center adjusting body 50 in step S24 and step S25. On the other hand, when it is not stopped in the state of facing the front, the swing center movement motor drive routine and the left and right swing motor drive routine are executed, and the vertical swing motor 80 is driven. If the fan head 69 is stopped in the state facing the front with respect to the swing center adjusting body 50 in step S25, the swing center moving motor drive routine is executed and the vertical swing motor is driven.
Drive 80.

FIG. 1 shows a motor drive routine for moving the swing center.
Describing on the basis of 4, the swing center position of the fan head 69 with respect to the base 1 is detected based on the output of the swing center position detection sensor 16 in step S26, and in step S27, the transmitter 84 calculated in step S18 It is determined whether or not the direction and the current direction of the swing center position match. If the direction of the transmitter 84 does not match the swing center position in step S27, it is determined in step S28 whether or not the fan head 69 faces the right of the direction of the transmitter 84 calculated in step S18. If it is, the motor 12 for swing center movement is driven in step S29 to drive the fan head 69.
Rotate the swing center of the to the left. The transmitter calculated in step S18 by repeating steps S26 to S29.
The direction of 84 and the position of the swing center of the fan head 78 are matched.

When it is determined in step S27 whether the swing center position of the fan head 69 and the position of the transmitter 84 match, the swing center position of the transmitter 84 calculated in step S18 is determined. Within a specified angle in the left-right direction centered on the position,
In the present embodiment, when the transmitters 84 are within the range of about 2 °, it is determined that the transmitter 84 and the swing center position are in agreement. Since the air blown by the blower fan 76 is diffused, it can be blown in a relatively wide range around the direction of the fan head 69, and within a range of about 2 °, the fan 84 can be moved without moving the fan head 69. Can be blown in the direction of. Therefore, it is possible to reduce unnecessary driving of the swing center moving motor 12 and improve durability.

In step S28, it is determined whether or not the fan head 69 is facing to the right of the direction of the transmitter 84 calculated in step S18. If it is not facing to the right, that is, to the left, step S30. For swing center movement in
12 is driven to rotate the swing center of the fan head 69 to the right. Steps S26, S27, S28, and S30 are repeated, and the direction of the transmitter 84 calculated in step S18 and the position of the center of swing of the fan head 69 are matched. During the movement of the swing center and during the adjustment of the direction of the fan head with respect to the swing center by the left and right swing motor drive routine described later, the wind direction adjustment display LED 29 provided on the switch panel 19 of the base 1 blinks to adjust the wind direction. It is supposed to display that it is inside.

When the direction of the transmitter 84 and the swing center position of the fan head 69 coincide with each other in step S27, step S31
Then, the motor 69 for moving the swing center is stopped at step S
At 32, it is determined whether or not the later-described left / right swing motor drive routine has ended, that is, whether or not the drive control of the left / right swing motor 43 has ended. Incidentally, when the process moves from step S20, S24, or S25 in the above-described wind direction setting routine to the swing center movement motor drive routine, that is,
The head of the fan is driven by controlling only the motor 12 for swing center movement.
When the 69 is directed toward the transmitter 84, the drive end signal of the motor 43 for moving in the left-right direction is input.

In step S32, the left and right swing motor 43
If the drive control of is completed, it is determined in step S33 whether the electric motor 74 is driven. If the electric motor 74 is not driven, the electric motor 74 is driven in step S34. Therefore, the fan head 69 can be rotated in the direction of the transmitter 84 and air blowing can be started only by controlling the wind direction adjustment switch 85 of the transmitter 84, and the operability can be improved. In addition, the electric motor 74 is driven after the fan head 69 faces the direction of the transmitter 84 to start blowing air, and it is not necessary to place the fan head 69 in the direction of the transmitter 84. There is no inconvenience such as blowing air to and scattering documents and the like.

Next, the left / right swing motor driving routine will be described with reference to FIG. 15. In step S35, the left / right swing motor 43 is driven, and in step S36, the head position detection sensor 65 causes the head wall position detection sensor 65 to cover the shield wall of the cam plate 44. Whether or not the end portion on the front end side of the rotation direction of 46 is detected, that is, the light emitting element 66 and the light receiving element 67 are detected.
When the head position detection sensor 65 detects the end of the shield wall 46, it is calculated in step S18 in the above-described wind direction setting routine in step S37. A left / right swing motor 43 drive timer is set based on the direction of the transmitter 84.

Head position detection sensor in step S36
If 65 does not detect the end of the shield wall 46 on the tip side in the rotation direction, whether or not the head position detection sensor 65 has detected the end of the shield wall 46 on the rear side in the rotation direction, that is, , The head position detection sensor 65 determines whether the end of the shielding wall 46 has come out between the light emitting element 66 and the light receiving element 67.
When the edge of the is detected, step S39
Based on the direction of the transmitter 84 calculated in 18, the left / right swing motor 43 drive timer is set.

In step S40, it is determined whether or not the left / right swing motor 43 drive timer set in step S37 or step S39 has expired. When the timer expires, the process proceeds to step S41 and the left / right swing motor 43 is moved. Then, in step S42, it is determined whether the drive control of the swing center moving motor 12 has been completed, that is, whether the swing center moving motor drive routine has been completed.

This left / right swing motor drive routine is executed in step S18 as described in the wind direction setting routine.
It is executed when it is determined that the direction of the transmitter 84 calculated in step 6 is above the range in which the fan head 69 can be directed to the blower 84 by driving the swing center moving motor 12, step S37 or step S37. The left / right swing motor 43 drive timer set in S39 drives the swing center moving motor 12 to rotate the swing center in the direction of the transmitter 84 to the rotation limit, The time for turning the angle of the difference between the limit and the direction of the transmitter 84 is set. Therefore, the transmitter should be placed at a position beyond the range of swing center.
When 84 is positioned, both the left and right swinging motor 43 and the swinging center moving motor 12 are driven, and the fan head 69 is transmitted to the transmitter.
Can be turned in 84 directions. Further, the left / right swing motor driving routine is executed even when the fan head 69 is not facing the swing center position, as described in the wind direction setting routine, and is set in step S37 or step S39. The left / right swing motor 43 drive timer is set to the time from when the left / right swing motor 43 detects the end of the shielding wall 46 of the cam plate 44 until the fan head 69 is directed to the swing center position. It is like this. Therefore, the left and right swing motor 43
And both the swing center moving motor 12 are driven, and the fan head 69 is directed to the swing center position by the left and right swing motor 43.
The head of the fan is directed to the transmitter 84, and the fan head 69 is transmitted to the transmitter 84.
Can be turned to.

Since the left and right swinging motor 43 and the swinging center moving motor 12 are driven at the same time, they can be quickly directed toward the blower 84.

Further, the position where the wind direction adjusting switch 85 of the transmitter 84 is operated causes the swing center to rotate to the rotation limit with respect to the base 1, and the fan head 69 rotates to the swing center. The position where the swing center is rotated to the rotation limit and the fan head 69 is rotated to the rotation limit with respect to the swing center if it is within a predetermined angle from the position where the swing limit is rotated. The fan head 69 is rotated up to. If it exceeds the above range,
The fan head 69 is not rotated, and the sounding device control circuit 118 operates the sounding device to generate an alarm sound to inform the user that the sound is being misused.

Next, the air volume setting routine will be described with reference to FIG. 16. In step S43, it is determined whether "strong" operation is being performed, that is, whether the electric motor 74 is operating at high speed, and "strong" operation is performed. If you are driving, step S
At 44, "light wind" operation, that is, the electric motor 74 is operated at an extremely low speed. If the "strong" operation is not performed in step S43, it is determined whether or not the "medium" operation is performed in step S45, that is, whether or not the electric motor 74 is in the medium speed operation, and the "medium" operation is performed. For example, "strong" operation is performed in step S46. If the "medium" operation is not being performed in step S45, it is determined whether or not the "weak" operation is being performed in step S47, that is, whether or not the electric motor 74 is operating at a low speed. In step S48, "medium" operation is performed. If the "weak" operation is not performed in step S47, the "weak" operation is performed in step S49.

The timer setting routine will be described with reference to FIG. 17. In step S50, it is determined whether or not the 4-hour timer is set. If it is set, the timer setting is canceled in step S51. Step S50
If the 4-hour timer is not set in step S52, it is determined whether or not the 2-hour timer is set in step S52. If it is set, the 4-hour timer is set in step S53. If the 2-hour timer is not set in step S52, step S52
At 54, it is determined whether or not a one-hour timer is set. If it is set, a two-hour timer is set at step S55. If one-hour timer is not set at step S54, at step S56. Set a one hour timer.

Between each step of each routine,
When the receiving unit 31 receives the infrared signal of the transmitter 84, the routine being executed is executed, the process again shifts to the main routine, and control based on the infrared signal received by the receiving unit 31 is performed.
